Martensitic stainless steels can be high- or low-carbon steels built around the composition of iron, 12% up to 17% chromium, carbon from 0.10% (Type 410) up to 1.2% (Type 440C): [8] The chromium and carbon contents are balanced to have a martensitic structure.
Elwood Haynes (October 14, 1857 – April 13, 1925) was an American inventor, metallurgist, automotive pioneer, entrepreneur and industrialist.He invented the metal alloy stellite and independently co-discovered martensitic stainless steel along with Englishman Harry Brearley in 1912 and designed one of the earliest automobiles made in the United States.
Martensite in AISI 4140 steel 0.35% carbon steel, water-quenched from 870 °C. Martensite is a very hard form of steel crystalline structure. It is named after German metallurgist Adolf Martens. By analogy the term can also refer to any crystal structure that is formed by diffusionless transformation. [1]
Maraging blades are superior for foil and épée because crack propagation in maraging steel is 10 times slower than in carbon steel, resulting in less frequent breaking of the blade and fewer injuries. [i] [20] Stainless maraging steel is used in bicycle frames (e.g. Reynolds 953 introduced in 2013) [21] and golf club heads. [22]
Virtually generated microstructure of dual-phase steel. [1]Dual-phase steel (DP steel) is a high-strength steel that has a ferritic–martensitic microstructure. DP steels are produced from low or medium carbon steels that are quenched from a temperature above A 1 but below A 3 determined from continuous cooling transformation diagram.
X46Cr13 is the European Norm name for a common martensitic stainless steel with the numeric name 1.4034. It is equivalent to American Iron and Steel Institute standard 420C . It has the highest carbon content of the SAE 420 series.
Legends of wootz steel and Damascus swords aroused the curiosity of the European scientific community from the 17th to the 19th century. The use of high-carbon alloys was little known in Europe [20] previously and thus the research into wootz steel played an important role in the development of modern English, French and Russian metallurgy. [21]
An example of such a phenomenon is the martensitic transformation, a notable occurrence observed in the context of steel materials. The term "martensite" was originally coined to describe the rigid and finely dispersed constituent that emerges in steels subjected to rapid cooling. Subsequent investigations revealed that materials beyond ferrous ...
